Fix CS7034: pin AssemblyVersion/FileVersion in OpenCvSharp.Analyzers.csproj

The repo's CI passes -p:Version=4.13.0.YYYYMMDD at pack time. That date
component (e.g. 20260524) exceeds ushort.MaxValue (65535), which is the
limit for each component of an AssemblyVersion. Setting AssemblyVersion and
FileVersion to a fixed 1.0.0.0 avoids the CS7034 error while leaving the
NuGet package Version free to use the date-based scheme.
